Referring tothe drawings, wherein. like reference characters throughout the several views, 5 represents WORCESTER, MASSACHUSETTS, CORPORATION 0F l indicate like parts i the last roll ofV apaper drier,'6 the drier belt- V whichpasses over said' roller, and 7 Va rollerv `under which the b'eltpasses as it travels through the drier. A web -8 of crepe paper or other material, after passing through'the drier, is Adirected by a guard 9 into the slit; ting and winding machine, said guard' being inountedjonthe frame piece 10` of the ma chine which also serves asa support forthe` slitting mechanism.

The slitting mechanism, together withthe; the Winding mechanism presently to be de scribed, lmay be driven from any desired source of powerby any suitable means not shown),an'd said slitting mechanismk (Figs.

1 andto-` vl1) preferably` comprises a shaft 11 Ajournaled in suitable bearings on the machine Yframework and Vhaving rigidly secured theretov at desired Aintervals a plurality' of circularslittersone of which is indicated at l2. These slitters are positioned on shaft 1l between collars l2', 12v and serve to cutt web 8 into a plurality'of narrower webs 8', 8', and for this purpose the web 8 is `passed under a roller lfjournaled onl frame'piece l0 and then between the slitters and a slitterboard 14'. Said board is pivotally'mountedv on the'machine so that, be-fore'the'same is started, the board may be turned downwardly from the slitters to the position shown in. `dotted lines, Fig. 8, to permit the web to be freely passed to and secured on the winding mechanism vby an attendant.

Referring to Figs. l, 7' and 8, the slitterl, y Y o board 14 is mounted between spaced clamps is a side elevation of the device.

15,15, rigidly secured on a shaft 16, eachend of which is journaled in a suitable bearing on;

an arm -16"of a pedestal 16" which consti-` tutes a part of the machine framework. Suitn ablel fastening means may be employed to Fig. 9 is a top-plan view off a Sltter bladeV lioldthe clamps securelyin engagement with through the clamps and board, one of said f boltsbeing indicated at 17."` A handlel 18 is rigidly secured as by a key 19 on a projecting end of shaft 16, and. when the handle is moved V.in a Vcounter-clockwise A'direction the board maybe turned to a vertical position, thereby lifting the web 8 into engagement l with the slitter blades 12; The slitter board is maintainedinoperative -relationfwit-h the s'littersfby fafstop pin`v 20 secured inf an extension `21 of pedestal arm 16k and r,by a `pawl `22 pivotally mounted at 2,3 insaid extension.

By `depressing the pawl'wagainstthe tension of spring '27,-vthe slitter-board can be turned to theright through the medium of handle 18thereby` moving theboard andv web 8out of icontactwith the slitters. The shoulder 26 thenfengagesfpin 20 whichythus serves as al" stop for .the board in its inoperativeposition.

The slitters` are provided `with afguard (Figs. 8' to 11) consisting of a guard plate 31. for 'each `slitter blade12, said plateV having an elongateddslot 32 ,through whichA the slitter bladetnormally projects. i The plates 31 are supported on-strips 33,33suitablyise-1 i `cured as by rivetsi34,` 34 to yL-ba'rsj 35435;

which `constitute part of the -slitter'guard frame. Spacingpieces 36,36 `are interposed between said strips andjthe-Lfbars, and the ends 'of each plate 31 `are engaged under L bars 35, 35 and secured between the latter and. strips y33, 33 by brackets 37, 37 vriveted at 38,38-130 the p1ate131 and havingsetscrews-39,39 which may befturned down into `engagement with` the4 horizontal flanges of- Lfbars 35, 35. f- The slitter'guard framefur# ther includes anV L-fbar 4,0V at eachfendftherelV of, andusaid `frame is pivotally `mounted at 41 on. a bracket 425secured to a cross-strut 43, preferably made of Ywoodfand l constituting part of Athe mafchinmframework. The pivotal .connection for the, slitter` guard frame withfcross-strut 43 vfurther .includes strap hinges, one of which; isindicated at 44 (Fig.

8) the same `being rivetedat under sidegof L.b,ar\40," i

The head46of a bolt` 47 serves as astop for. theslitterj guard when the'slitter bar. is turnedl to its inoperative Aposition indicated by dotted lines inEig. 8. Saidvsbolt passes 45, 45 to the throughfa suitablepaperture -in the slitter,

guard frameand issecured. by nuts 48 and 49 in a ,bracketed extension i. 50 of thefmachine framework. l It will thus appear that when the slitter-board is returned to its inoperative position, ythe slit-ter guard will drop to a position removed from or below the edges of the .slitter blades and into engagement with'the head 46 of bolt 47. The web 8 canthen rbe passed by an attendant into the machinewithout dangerv of his handsor the web cominginto Contact with the slitters. Whenv the 'slitter-board is turnedjup toflift the web into Contact With'theslitter blade,

, said board raisesthe slitter guard to the full line position of Fig. 8 and supports the same in suchfposition whilejthe web is being Aslit into the plurality of narrower webs 8, 8. Sidewise movement or 'displacement Vof Vthe web withrespect to the slittereboard is prevented by a. guide 51 at'each end ofthe board,

said guides being secured to the board byV any suitable .fastening meansrsuch as a bolt 52 and nuts 53, 54.` AThe guides 51 have curved i upper/edges which engage the under side of theguard beneath Vthe L-bars 40,40. at opposite sides thereof, as shown in Fig. 11, and theV guard is supported on said curved edges Vof theguides and raised and lowered thereby whenthe slitter board14 is raised to the full line position shown in Fig. 8, or lowered to x the dotted line position shown in said ligure..

`According to the present invention, suit-` pass fromthe slitting mechanism to the winding mechanism. Said spreading means preferably comprises plurality of spreader bars 55,55, one for eachof the several webs 8',

,8-,(rFigs.12iandv 8). i Each bar 55 is provided longitudinally thereof with a suitable groove vventedV from rotating by reason ofthe squared fit between the shank 58 and the col.- lar 60. The spreader bar operating shafts extend vertically through suitable spaced openings` of the cross-strut 43, the threaded partY 59 lof each shaft extending through an opening in a flanged collar 62 secured to the cross-strut as by screws 63, 63. Each spreader 'bar operating shaft is provided with a handwheel 64y threaded thereon and by means of .which the bar can be raised and lowered throughthe' turning movement of said wheel. 'It will thus appear that the several spreader bars can be moved vertically to different positions with respect to each other f able meansv are employed for.` spreading the web Vor Webs of material vertically as the samev that the'several .Webs 8, v8l Willl be separated or spread apart vertically fromy thev dium of a carriage 66. .Said carriagezis ar'- ranged for movement transversely of themachine `along a traclr67, and for-this purpose the carriage is provided With a grooved. roller 68 which engages the track and isprevented from displacement by a guard 69. In order to start roll 70, the slitter-board 14 is turned down and web 8 is passed by an attendant through the machine over a 'winding drum 71, 'rotating in` the direction of the arrow' i (Fig. 1). Y The Winder bar is then dropped from its carriage into supporting' means ad' jacent the drum so that? the Winder bar' rests onthe web and-drum." The free end of the weblisv then turned onto the Winder bar and the roll started by rotation Yof the drum 71. Passing of the Web can be performed While the-machine is in operation and after the roll 70 is started the slitter-board isv raised, therebyr lifting the Web into contact With cutters 12 Which sever web A8 into webs 8', 8. The spreader bars are then lowered into engagement with Webs 8', 8 at dierent positions so that the Webs will be spread as above del scribed.- The rollvv70 is thus constituted by a plurality of individual smaller rolls wound in end toI end relation on bar 65.

Drum/71 is mounted on a shaft 72, each end of which is'journaled ina suitable bearing 73, secured to a frame piece 74' of the machine.A

The means for supporting the Winding bar 65 in operative relation with drum 71 preferably comprises swinging' supporting.' arms dis posed one at each side of themachine andr arranged for movement so that-the roll 70 and its contained Winder bar may be caused toV travel over the; surface of Winding drum 71 between'the full andY dotted line positions of the roll indicated respectively at A and C (Fig. 1)'. Said arms* are provided With suitable mechanism for ymoving the same in the manner above indicated and are further equipped with devices which automatically grip andrelease the Winder bar; Since the construction ofthe Winder bar supporting arms,-the"means for movi-ng'thesame, and the:`

associated gripping and releasing' devices are identical at both sidesof the machine, itkis only nec'essaryft'o'describe the mechanism located adj'acentoneside-thereof. Each arm 75 providing jaw portions 77, 7 7 and asegmem tal gear7 8 formed in or secured to a Web-like part of the arm. The arm 75 is rigidly secured on shaft 72 adjacent vone extremity thereof through `the medium of collar 76 and setscrews threaded into suitable bosses on the split Ycollar sections. One of these set-screws and the corresponding bosses are indicated respectively at'7 9 and 79', 79- inFig. 4. The segmental gear 78 engages a pinion 80 rigidly secured on a shaft 81 extending transversely of the machine and journaled in suitable bearings, one of Which is indicated at 82. Bearing 82 is formed on arm 16 andthe shaft-81 projects outwardly through said'bear'ing and has secured thereon a ratchet 83 4and a handwheel 84. The hand-Wheel serves to rotate :the shaft 81 Which, through the medium of pinion and segmental gear-78 rotates the arm 75 so that roll 7 0 may be moved over the surface of kdrum 71 as above described. l A, pawl 85, pivoted at 86 on the bearing 82, serves to prevent backward movement of the arm 75 and the roll 70 When the two are being; moved, for example, from the initial winding` position A yto the intermediate and fina-l positions indicated respectively at B and C. Said pawl is manually released to permit movement of the arm from position B to position A in order to start a new roll. I 5 r At` each end the Winder bar65 has portions 87 and 88 of relatively :different diameters, and when the Winder bar is dropped intol its supporting arms' 75 between aw' portions77, 77, portion 87 initially rests on the bottom89 of the jaw' provided by portions 77, 77.` A lever 90 ispivotedrat 91 in an offset portion or boss 92 formed on one of the jaw portions 77 and said lever is provided with a paWlQS. Vhen theA Winder'bar is dropped into place as above described,the extention 88 tripsrlever 90 thereby di'sengaging the pawl from a ratchet94 located at one side ofthe jaw 77,V

77 and-secured as by a key 95 on a shaft 96 Vjournaled in a suitable bearing in boss 92.

90 is tripped and pawl 93`disengaged from' ratchet 94, lever 97 is thrownfrom a substantially vertical position into engagement. with extension 87`of the Winder bar through the mediums of a coiled spring. 98, one: end .of which is engaged invasuitable aperture 99 formed in ank offset portion 100 oflever 97. rIhe opposite extremity. of spring 98 is engaged in the aperturedend of a bolt` 101 threaded into aboss 102 formed on one -of the sections of split collar. 7 6, said bolt serving to ust the tension of spring. 98 and being secured in its adjusted position by means ofanut108.Y Y 1 The tensionof spring 98 on lever 97 pro;` duces, a pressurev ofthe latter on the Winder bar,`which tension and pressure serve, particularly atthe time' winding of roll 70 is started,to produce a uniform hard roll. Y As the roll70 builds-up at position A the winder bar 65 gradually moves away frein-the sur- Y portions 77, 77, aclip vspring 104 secured'at face of roll7 land raises'lever against the tension of spring-98 4thereby moving ratchet 94 in a counter-'clockwise directon'past, pawl 93. :When thewinder bar moves out off-jaw 105, 105 `to one of said portions, maintains pawl 93 1n engagement with' ratchet'` 94- so that thetension ofi-spring 98"cannot move lever` 97 back past jaw portions77, 77 until another winderbar is .inserted therebetween andengaged withlever 90,atwhich time the latterk will againbetripped lso that thejabove described operations may be repeated `at position A.

HWV-hen .the rol17 01 has been builtfup tor a driameter of say lapproximately'six inches the same is moved fromp'osition Ato position` B and-then to position C byv means of the supporting arm operating mechanism above described. Previous .to the arrival `of .roll 70 at .position G9a hingedsection k106 ofv a vvertical guidel07 isflifted to the dotted line position shownin Fig. 1,where guide Vsection 106 may be 'supported by engaging a .hook 108 with a pini109 suitably secured on said section adjacent :the free-extremity.thereof; The lower part of guide 107 being opened,`the end of the'winder bar is received in said guide, the

roll 70 ,thenirestingl onwinding drum 71 and an auxiliary iutedwinding drumr110 rotated by any suitable means (not shown) at a'surface speed corresponding to thatof drum 71.

.Hook- 108 is then disengaged from guidesecl tion 106l and the latter allowed to dropdownvao wardly'to the full line position shown in Fig;v 1,the-guide section 106sbeing maintained in its-closed positionV by adetent 111 which engages pin 109. The auxiliary winding drum 110 is'mounted-on a shaftllQ, the end of t to` lift or move lever 97 to one side ofthe builds saidA rollfup to the desiredv size, ndi-4 cated lfor example by the 'large` dotted circleV atthe left of Eig. 1, and causes the Winder Abar jaws 77, 7 7 ofthe Winder bar supporting arm where, after thetwinder barbas-passed out of the jaws, said lever is retained andlprevented from snapping back .past said jaws Vby the paWl/93 and ratchet 94. `The winder bar supporting `arm is then returned to position Aby rotating hand-wheel 84 andan empty WinderVv bar passed into the machine, through the medium of carriage 66, for association with the Winder bar supportingarm and the startingiof anew roll. i i Y, The Winder bar containedwithinthe roll winding atposition C, gradually rises within guide 107 whichservesto' maintain said roll in proper position with respect to drums71 and110. v lhen said r'oll reaches the desired size, 'the `slitter-board is lowered and the spreader bars raised. The web is then severedfrom the; roll'betweenthe slitting and winding mechanisms so as to'leave a free end extending over winding drum 7l. The empty winding bar is then dropped onto the web: andldrum and the bar engaged with the supporting arms yas` previously described. The free `end oftheweb is then passed around said `bar to start the new roll. The winding operation again proceeds at positionA and the slitter-board is raised and the spreader bars lowered so that the web forming the new roll is severed and the portions thereof spread vertically as the material is being wound on the secondbarf *The` finished rolls can be removed from the machine Ain'any desired manner,.asv by lifting or rolling the same outof the machine manually,or,through the medium of any suitable'mechanism adapted to accomplish `this purpose. v `.lVhat is claimed is: Y
